Start at the beginning of electrolytic cell, carbon lining selective absorption of sodium fluoride, the electrolyte molecular ratio declined sharply, with the adjustment of more than sodium fluoride molecules; in addition, slots with molecular synthesis of cryolite ratio is too low, to adjust to the requirements of the use of molecular ratio, also need a large amount of sodium fluoride mixture. In addition, it is also widely used in the coating industry as phosphating accelerators, agricultural pesticides, sealing materials, preservatives and other fields. Used as agricultural pesticide, wood preservative, metal flux, analysis reagent, also used in machinery for the inserted steel welding fermentation equipment, manufacturing of fluorine compounds. [storage] in ventilation, shade, sunscreen, moisture-proof and rain-proof place.
